Wood & Timber Retaining Walls
Pressure-treated lumber and hardwood timber retaining walls — natural look that blends beautifully with landscaping and gardens in London and Southwestern Ontario.
The Natural Choice for Landscape Retaining Walls
Wood and timber retaining walls offer a natural, organic aesthetic that concrete and block simply can't match. For garden terraces, raised planting beds, residential landscape features, and low-to-medium height grade changes, wood walls are an excellent choice — and they're often more economical than concrete or block.
The key to a long-lasting wood retaining wall is using the right materials, proper post depth, adequate drainage, and correct construction technique. A well-built wood wall with good drainage will give you 20–40 years of service.

Frequently Asked Questions
How long do wood retaining walls last?
Pressure-treated wood retaining walls typically last 20–40 years depending on wood grade, drainage quality, and maintenance. Hardwood timber walls (using oak, black locust, or similar) can last 30–50 years. Proper drainage is the biggest factor in longevity.
What type of wood do you use for retaining walls?
We use CA-B or better pressure-treated lumber for standard garden walls. For walls that require higher durability or a more natural aesthetic, we can use hardwood timbers including oak, black locust, or similar species.
Can wood retaining walls be stained or sealed?
Yes. Pressure-treated wood can be stained or sealed once it has dried out (typically 6–12 months after installation). This can help preserve the wood and achieve a desired colour. We recommend using a penetrating oil-based sealant for best results.
Are wood retaining walls good for garden areas?
Yes — wood and timber walls are particularly well-suited for garden terraces, raised beds, and landscape areas where you want a natural, organic look. They blend beautifully with plants and landscaping in a way that concrete and block sometimes can't.
